Abstract

Absolute metrology techniques have been proposed for and used in a variety of optical systems as a means of precisely measuring distances. Typically the metrology concepts utilize frequency stabilized multiple wavelength lasers. We describe a multi-wavelength approach that utilizes the strengths of Photonic Integrated Circuits (PIC) to implement an absolute metrology sensor. The metrology sensor is a self-contained system that forms a multi-wavelength distance measuring interferometer. The PIC includes the waveguide circuitry, laser source, detectors and a National Institute of Standards and Technology (NIST) traceable reference in a compact form. The PIC is a hybrid combination of Indium Phosphide circuitry with active elements (detectors and laser) and a passive Silicon Nitride circuit of waveguides. The PIC implementation is presented along with measurement results showing an unambiguous range of 30 mm with nanometer precision.
